In an email template, a float with 5 decimal places is rounded to 2 decimal places

I have a float number with 5 decimal places. When I load it into the email template, it is rounded to 2 decimal places. It is important for me to have exactly 5 decimal places because this is the price of the quote and accuracy is very important. Help me, please. How to fix it?

Already looked at all PHP files where there is "round", but did not find which function is responsible for loading data into a placeholder of Email Template

This is the placeholder in the template
